Mongolian Short-toed Lark vs Asian Short-toed Lark

The Mongolian Short-toed Lark and Asian Short-toed Lark are both small larks found in overlapping regions of Asia, but they can be distinguished by subtle differences in structure and behavior. The Mongolian Short-toed Lark is more closely related to Hume's Lark, while the Asian Short-toed Lark has distinct migratory patterns.

1. Look for flocking behavior in nonbreeding Mongolian Short-toed Larks. 2. Listen for vocal differences if familiar with Greater Short-toed Lark songs. 3. Note the breeding range: Mongolian Short-toed Lark in eastern Mongolia and adjacent regions.

Both species are similar in size, typical of small larks, making size an unreliable distinguishing feature.

Plumage differences are subtle; both species exhibit typical lark browns and streaks. The Mongolian Short-toed Lark may have slightly more pronounced streaking on the breast, but this is not a reliable field mark.

The Mongolian Short-toed Lark is known to be highly gregarious in the nonbreeding season, often forming large flocks, which might help in distinguishing it from the Asian Short-toed Lark.

Both species inhabit open, dry areas such as steppes and grasslands. The Mongolian Short-toed Lark breeds in eastern Mongolia and parts of China and Russia, while the Asian Short-toed Lark's range is less specific in the notes.

The song and calls of the Mongolian Short-toed Lark differ markedly from those of the Greater Short-toed Lark, but specific comparisons with the Asian Short-toed Lark are not detailed.
